SMB3Z8.2A from ZHIDE, in a SMB. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode, marked by the color band on the package; positive terminal in zener (reverse-breakdown) operation, with VZ of 7.79 V min, 8.2 V nominal and 8.61 V max for SMB3Z8.2A. |
| 2 | A | passive | Anode, the terminal opposite the color band; maximum forward voltage is 1.2 V at 200 mA and DC power dissipation is 3.0 W at TL = 75 °C. |
